• Chaging SITECONF settings
• CRAB3 mantra

T2

• Base improvements in the T2 cluster management schema -- will improve the cluster stability and ease maintenance procedures

• Explore dynamic Condor job scheduling based on resource utilization and job requirements. Condor will not anymore serve X slots, but will schedule jobs as long as CPU usage is < 90% (configurable) and there is enough available memory in a node. In general this should provide slightly more job slots than the number of cores that a node has. -- motivation : most of the jobs have CPU efficiency < 70%

• Improve BeStman GridFTP selection algorithm (light development needed) -- currently round-robin, very sub-optimal for setup like ours where we have fast (10 GE) servers and slow (1 GE) servers.
